<font color='#000000'>Maybe not in general or totally. There are many exceptions. Like I said, price could be just an indication. Weight on the otherhand, when talking of amos, can be more indicative of better built and dynamic power ability courtesy of a generous power supply for which the use of large and heavy transformer, whether conventional or toroidal, is an indication. Added weight as a result of the use of metal chassis, rather than plastics, does not generally augur for good sound, though many brands claim they result in better interference shielding, but rather, they, in my experience, speak of better built and handling durability. These specs can make an amp more expensive than one that doesn't use them. Afterall, it is generally held that you deserve to get what you pay for, right?</font>
